Yip, finally as you and Myles suggested adding the vga rom to the cbfs manually made SeaBios find it. The only thing is that I had to go back to SeaBios 4.2 because 5.0 wasn't still able to get it right. Btw, yes it this a onboard vga (ATI 1000ES).
That's odd. Can you forward the log files (debug set to 8) from SeaBIOS v0.5.0
Scan for VGA option rom Checking rom 0x000c0000 (sig 0 size 0) init usb
and SeaBIOS v0.4.2?
Scan for VGA option rom Attempting to init PCI bdf 01:01.0 (dev/ven 515e1002) Searching CBFS for prefix pci1002,515e.rom Found CBFS file normal/payload Found CBFS file normal/coreboot_ram Found CBFS file fallback/payload Found CBFS file fallback/coreboot_ram Found CBFS file pci1002,515e.rom Copying data 45056@0xfff3c9f8 to 196608@0x000c0000 Checking rom 0x000c0000 (sig aa55 size 88) Running option rom at c000:0003
It looks like 5.0 doesn't have CONFIG_OPTIONROMS_DEPLOYED set to 0. It's looking in RAM instead of in CBFS.
Thanks, Myles
